Hello and welcome to ExamPundit. Here is a set of Quantitative Aptitude Quiz for Bank and Insurance Exams. These are based on Quadratic Equations and Number Series.
Directions (Q. 1-5):In each of these questions a number series is given. What value will come inplace of the question mark (?) inthe following series?
1. 0.5 ? 1.5 4.5 13
38.75
38.75
(a) 0.5
(b) 0.75
(c) 1
(d) 1.5
(e) None of these
| Solutions -(.5 + .5) × .5 = .5 (0.5 + 1) × 1 = 1.5 (1.5 + 1.5) × 1.5 = 4.5 (4.5 + 2) × 2 = 13 (13 + 2.5 ) × 2.5 = 387.5 |

4. 11 24 16 38 27 64
?
?
(a) 34
(b) 38
(c) 44
(d) 36
(e) None of these
| Solutions -11 × 2 + 2 = 24 24 ÷ 2 + 4 = 16 16 × 2+ 6 = 38 38 × 2 + 8 = 27 27 × 2 + 10 = 64 64 ÷ 2 + 12 = 44 |

5. 821 460 749 580
701 652 ?
701 652 ?
(a) 668
(b) 677
(c) 766
(d) 686
(e) None of these
| Solutions – 821 – 192 = 460 460 + 172 = 749 749 – 132 = 580 580 + 112 = 701 701 – 72 = 652 652 + 52 = 677 |
